What "specialized" actually means for interior drainage system at our company — not a marketing word, a set of specific practices.
Technicians are specifically trained in slab coring, drain tile installation, and sump basin integration — a distinct skill set from exterior excavation work.
Crews carry core-cutting equipment and basic drain tile stock, so assessment and the start of installation can often happen on the same visit.
No hourly billing — if the job scope changes once the slab is opened, we discuss it with you before proceeding.
We coordinate installation to minimize disruption to finished basement spaces wherever possible.
Each service below is scoped specifically to interior drainage system, not a generic waterproofing menu with the name swapped in.
The channel is sloped precisely toward the discharge point so water flows by gravity rather than pooling within the drain tile itself. New concrete is poured back over the channel, restoring a finished, level floor surface.
This method is faster to install than full drain tile and works well for moderate, consistent seepage rather than significant hydrostatic pressure.
We calculate expected inflow volume based on perimeter length and water table conditions before recommending pump horsepower.
Interior drainage systems address this joint directly, capturing water at the source rather than letting it spread across the floor first.
Collected water needs to exit the sump basin and the property entirely — we route discharge lines well clear of the foundation with a check valve to prevent backflow into the system.
Here's the exact path from your call to a completed interior drainage install.
